Fuel Requirements for Lexus LS 460

The Lexus LS 460 is a high-performance luxury sedan that boasts a powerful engine and advanced engineering. As such, it is designed to deliver optimal performance when fueled with premium gasoline. The official recommendation from Lexus is to use fuel with an octane rating of 91 or higher for the LS 460.

While the vehicle may run on regular unleaded gasoline with an octane rating of 87, this is not the optimal choice for maintaining the vehicle’s performance and efficiency. Using lower octane fuel than recommended can lead to engine knocking, reduced power output, and diminished fuel economy.

Benefits of Using Premium Gas

Opting for premium gasoline, with its higher octane rating, can provide several benefits for your Lexus LS 460:

  • Enhanced Performance: Premium gas allows the engine to operate at its full potential, delivering the performance and responsiveness that Lexus drivers expect.
  • Improved Fuel Economy: While the upfront cost of premium gas may be higher, it can contribute to better fuel efficiency, offsetting the price difference to some extent.
  • Engine Protection: The higher octane rating in premium gas can help prevent engine knocking and pinging, safeguarding the engine components and promoting longevity.
  • Optimized Emissions: Premium fuel can contribute to lower emissions, which aligns with environmental considerations and regulatory standards.

Cost Considerations

While it’s clear that using premium gas offers several advantages for the Lexus LS 460, it’s understandable that some owners may be concerned about the associated costs. Premium gasoline typically comes with a higher price tag compared to regular unleaded fuel.

However, when evaluating the overall cost of ownership, it’s crucial to consider the long-term benefits of using premium fuel. The potential savings from improved fuel economy, coupled with the protection and performance advantages, can outweigh the initial price disparity.

Owner’s Manual Guidance
